I haven't tried other usb to midi's but on the line 6 website they recommend the maudio midi sport UNO bec it works flawlessly on the m13 and m9. Ive used it on my M13 without any trouble. These things can be very picky sometimes and with a mismatched cable it can cause a lot of confusion and agitation. So a cheapo midi - usb may only cause frustration when you do the update or it may even crap out while doing the firmware update.
